[0002] The controller and the motor share a heat dissipation channel. The coolant first passes through the controller to dissipate heat from the power module inside the controller, and then enters the motor to dissipate heat from the stator windings in the motor. The coolant absorbs the temperature inside the controller. Then enter the motor, the heat dissipation effect of the coolant will be reduced; in addition, in different regions, the temperature of the coolant is different, and the temperature of the coolant will also increase in places with high temperature, which will easily lead to excessive temperature inside the controller or the motor. Cause the module or motor to not work properly

The invention discloses an automatic temperature-adjusting heat dissipation water channel applied to an electric drive system. The automatic temperature-adjusting heat dissipation water channel comprises a first channel, a second channel, a controller, a motor, an electric adjusting valve and a one-way valve. First cooling liquid passes through the interior of the first channel, and second coolingliquid with the temperature lower than that of the first cooling liquid or easy to gasify and absorb heat passes through the interior of the second channel; the first cooling liquid in the first channel exchanges heat with the second cooling liquid in the second channel; the first channel and the second channel pass through the controller and / or the motor; the electric adjusting valve and the one-way valve are arranged on the second channel; and the electric adjusting valve is connected with the controller and / or the motor and used for receiving temperature signals of the controller and / or the motor and automatically adjusting the size of the one-way valve according to the temperature signals. The size of the one-way valve on the second channel is automatically adjusted by the electric adjusting valve according to the temperature signal, so that the temperature stability of a motor or a controller in the electric drive system can be ensured.
